Abstract (en)
[origin: US4918487A] A method and apparatus for applying liquid toner to fractional areas of a photoconductive recording member in processes involving microimagery. The method includes the steps of providing a photoconductor disposed over a conductive substrate having at least one fractional area thereon that is to be toned, providing a carrier member having a conductive layer, electrostatically depositing liquid toner on the carrier member to form thereon a toner pre-deposit of desired density in an area corresponding to the fractional area to be toned on the photoconductor, contacting the toner pre-deposit on the carrier member with the fractional area on the photoconductor, and toning the fractional area on the photoconductor by transferring toner thereto from the toner pre-deposit so that the quantity of liquid transferred to the photoconductor is minimal and can be rapidly removed therefrom without affecting the toner pre-deposit on the photoconductor. The apparatus includes backing members for supporting the photoconductor and contacting the fractional areas on the photoconductor with the fractional toner predeposits on the carrier member.
